Introduction to Red Line Torpedo Barbs (Puntius denisonii)

The Red Line Torpedo Barb, Puntius denisonii, also known as the Denison Barb, is a striking freshwater fish native to the fast-flowing streams and rivers of India. Renowned for its vibrant red line that runs through its body and torpedo-shaped form, this species is a popular choice for aquarists seeking to add colour and movement to their aquariums. This guide offers essential care tips for maintaining healthy Red Line Torpedo Barbs.

Optimal Water Conditions

Red Line Torpedo Barbs thrive in water temperatures between 18°C to 26°C, with a pH level of 6.5 to 7.5. They prefer soft to moderately hard water, emphasising the need for stable conditions and clean, well-oxygenated water. Regular water changes and efficient filtration are crucial to maintain water quality and replicate their natural habitat.

Aquarium Setup

A minimum tank size of 200 litres is recommended for Red Line Torpedo Barbs, as they are active swimmers and enjoy living in groups. The aquarium should include ample open swimming areas as well as hiding spots provided by rocks, driftwood, and dense vegetation. A strong current mimicking their natural riverine environment will help keep them active and healthy.

Diet and Feeding

Red Line Torpedo Barbs are omnivorous, requiring a varied diet that includes high-quality flake foods, pellets, and live or frozen foods such as brine shrimp, daphnia, and bloodworms. Vegetable matter, like blanched spinach or courgette, should also be included in their diet. Feeding small amounts 2-3 times daily is recommended.

Social Behaviour and Compatibility

Known for their peaceful nature, Red Line Torpedo Barbs are excellent for community tanks with other similarly sized, peaceful fish. They thrive in groups of six or more, which helps promote natural social behaviour and reduces stress. Avoid housing them with large, aggressive species that may intimidate or prey upon them.

Breeding Red Line Torpedo Barbs

Breeding Red Line Torpedo Barbs in captivity can be challenging due to their specific water condition requirements. A separate breeding tank with optimal conditions may encourage spawning. Subdued lighting and a diet rich in live foods can also stimulate breeding behaviour. After spawning, it is advisable to remove the eggs to a nursery tank to ensure their survival.

Conclusion

The Red Line Torpedo Barb is an attractive and lively addition to the freshwater aquarium, offering a unique blend of beauty, speed, and grace. With proper care, including suitable water conditions, a nutritious diet, and consideration of their social needs, these barbs will thrive and bring dynamic colour and activity to your aquatic environment.
